The QFX5100 line includes four compact 1 U models and one 2 U
model, each providing wire-speed packet performance, very low
latency, and a rich set of Junos OS features. In addition to a high
throughput Packet Forwarding Engine (PFE), the performance
of the control plane running on all QFX5100 models is further
enhanced with a powerful 1.5 GHz dual-core Intel CPU with 8 GB
of memory and 32 GB SSD storage.
QFX5100-48S
: Compact 1 U 10GbE data center access switch
with 48 small form-factor pluggable and pluggable plus (SFP/
SFP+) transceiver ports and six quad SFP+ (QSFP+) ports with
an aggregate throughput of 1.44 Tbps or 1.08 Bpps per switch.
QFX5100-48T:
Compact 1 U 10GbE data center access switch
with 48 tri-speed (10GbE/1GbE/100 Mbps) RJ-45 ports and six
QSFP+ ports with an aggregate throughput of 1.44 Tbps or 1.08
Bpps per switch.
QFX5100-24Q
: Compact 1 U high-density 40GbE data center
access and aggregation switch starting at a base density of 24
QSFP+ ports with the option to scale to 32 QSFP+ ports with two
four-port expansion modules. All 32 ports support wire-speed
performance with an aggregate throughput of 2.56 Tbps or 1.44
Bpps per switch.
QFX5100-24Q-AA
: Compact 1U high-density data center
switch starting with a base density of 24 QSFP+ ports. With the
addition of an optional double-wide QFX-PFA-4Q Packet Flow
Accelerator (PFA) expansion module, the switch can morph into
an intelligent application acceleration system. Alternatively,
by installing two four-port 40GbE expansion modules, the
QFX5100-24Q-AA can expand to support 32 QSFP+ ports. The
switch’s CPU subsystem is enhanced with a quad-core Intel CPU
with 32 GB of DRAM; additional storage capacity is provided via
an onboard 128 GB solid-state drive. The QFX-PFA-4Q features
an Altera Stratix V 320 Gbps FPGA with 24 GB SDRAM (DDR3)
for packet memory and 72 MB of quad data-rate static RAM
(SRAM) (QDR2+) for low-latency processing.
